Verified step by step guidance1
Understand that the atomic mass of an element is the weighted average mass of all its naturally occurring isotopes, measured in atomic mass units (u).
Recall that silver (Ag) is a transition metal with an atomic number of 47, which helps to identify it on the periodic table.
Look up the atomic mass of silver on the periodic table or in a reliable chemistry reference; it is typically around 107.87 u.
Compare the given options (63.55 u, 107.87 u, 118.71 u, 47.87 u) to the known atomic mass of silver to find the closest value.
Select the value that matches or is closest to the known atomic mass of silver, which is approximately 107.87 u.
